Please guide on my 5 day plan Interlaken + Zurich

I am sharing the itinerary i have planned for June 2016 for 4 people. We are coming from India. Kindly advise and help me improve the Itinerary , Inter city Travel plan and Shopping plan. I also have some additional questions at the end. :)

Most of your itinerary looks fine. Please note that Gstaad is quite far from Interlaken, and I don't think you should include this. Focusing on the Zurich, Interlaken and maybe Lucerne regions is much better for such a short stay.

As for your questions:

1/2/5. You can find all travel details in the timetable at myswissalps.com/timeta ble. Just enter your departure and arrival station (or hotel address), a preferred travel time and all options will be displayed. The timetable for June 2016 isn't available yet (it will be in a few weeks), but you'll be able to get a good impression using the current timetable. The trip up to the Jungfraujoch is also described at myswissalps.com/jungfr aujoch/gettingthere.

3. Your itinerary is quite full the way it is now, so there's not that much more you can add. Especially day 3 is long. You may want to replace Titlis with a scenic trip a lot closer to Interlaken. Ideas can be found at myswissalps.com/jungfr auregion/activities. Tips for your stay in Zurich are listed at myswissalps.com/zurich.
